Friends of Yellow Creek
Yellow Creek is a tributary of the Cuyahoga River in Northeast Ohio.  It has been rated as one of only two high-quality tributaries of the Cuyahoga River, but it is also threatened by effects of development.  Recent data indicate that water quality may be declining.

As described in the Mission statement, the Friends of Yellow Creek aim to help in the effort to preserve the good, remediate the bad, and educate.
